Milestone A follows which phase?

• A. Material Solution Analysis Phase
• B. Operational testing phase
• C. Production readiness phase
• D. Disposal phase

Answer: (A)

Milestone A is the decision point that allows a program to move from evaluating options to actively developing a chosen solution. In the acquisition process, the Materiel Solution Analysis phase is where capability needs are clarified, alternatives are considered, and a preferred solution is identified along with initial cost and risk assessments. Once that phase is completed, Milestone A authorizes entry into the Technology Development phase, where the chosen solution is matured through design, prototyping, and risk reduction activities. The other phases—operational testing, production readiness, and disposal—occur later in the lifecycle, so Milestone A comes after the Materiel Solution Analysis phase.
